“It is with beyond a heavy heart that Duck Down Music is sadly confirming that Sean Price passed away early this morning in his Brooklyn apartment,” a rep for Price said in a statement, according to the magazine.

“The cause of death is currently unknown, but it was reported that he died in his sleep.”

The statement continued: “Sean’s family and friends are asking for time to grieve and process the news. Further details will be issued when more information is available.”

Calls to Price’s rep were not immediately returned.

Price’s career began as “Ruck,” one half of Heltah Skeltah, alongside Jahmal Bush as “Rock,” a fellow Brooklyn native. They released their debut, Nocturnal, in 1996, and both rappers were also part of Boot Camp Clik, a hip-hop supergroup.

Price also performed in Random Axe, with Guilty Simpson and producer Black Milk; and his solo career included three albums under his own name, with the last, Mic Tyson, in 2012.

He was slated to release a mixtape, Songs in the Key of Price, on Aug. 21.

Members of the musical community have quickly shared their condolences.
